New reports have surfaced claiming an emergency meeting was held Wednesday at Buckingham Palace.

According to the Daily Mail, the Queen's most senior aids called the royal family member's entire household for a meeting.

Servants from royal residences across the country have also reportedly been ordered to London.

While there is no confirmed reason for the sudden gathering, it hasn't stopped speculation both in and around London.

"Although meetings involving the entire royal household are occasionally called, the way this has been done at the eleventh hour is highly unusual and suggests that there is something major to be disseminated," a source shared with the Daily Mail. "But at the moment, only those closest to her genuinely know what on earth this is all about."
